This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

Este Web site contiene links a 12 calendarios (12 meses). Cada mes contiene actividades sobre matemáticas.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
